Got the game. I opened the Iso file with ISOultra. Extracted it. Used Nero to burn files on to a dvd as dvd data. Installed game, copy patch in folder in the C drive. Put disc in started game. Played fine (missing the short movies they show, hear it can't see it ) got to level 2. clicked start mission. Froze up. Try uninstalling & reinstalling. Tried burn a new DVD & reinstalling it. Now level one won't start. Freezes up. What going on? Please help.
